Abstract

Abstrak Ketidakseimbangan nutrisi dan kualitas tidur yang buruk, masih sering ditemukan pada siswa SMK. Hal ini berdampak langsung terhadap kesehatan fisik, mental, serta pembentukan karakter. Survei internal pada 176 siswa SMK Telkom Banjarbaru menunjukkan tingginya angka depresi dan gangguan mood, yang mengindikasikan perlunya intervensi edukatif untuk meningkatkan kesadaran mengenai pentingnya pola hidup sehat. Kegiatan pengabdian ini bertujuan meningkatkan pengetahuan dan keterampilan siswa dalam memahami kesehatan mental, membangun karakter disiplin berkelanjutan, serta menyusun menu nutrisi seimbang sesuai prinsip “Isi Piringku”. Mitra kegiatan adalah SMK Telkom Banjarbaru dengan jumlah peserta sebanyak 182 siswa kelas X. Metode pelaksanaan meliputi ceramah, diskusi, simulasi praktik penyusunan menu, serta evaluasi pretest dan posttest. Hari pertama difokuskan pada edukasi mengenai kesehatan mental, karakter, dan hubungan nutrisi dengan kondisi psikologis, sedangkan hari kedua berisi pelatihan penyusunan menu sehat dan jurnal pola makan. Hasil kegiatan menunjukkan adanya peningkatan pengetahuan siswa pada seluruh materi, yang ditunjukkan melalui  perbandingan skor  pretest  dan  posttest.  Kegiatan  ini  juga  mendorong siswa  lebih  aktif berdiskusi dan reflektif terhadap kebiasaan hidup mereka. Secara keseluruhan, program edukasi dan pelatihan ini dapat meningkatkan pengetahuan siswa mengenai pola hidup sehat serta keterampilan menyusun nutrisi seimbang sebagai bagian dari pembentukan karakter yang berkelanjutan. Kata kunci: edukasi; hidup sehat; kesehatan mental; nutrisi; pendidikan karakter. Abstract Nutritional imbalances and poor sleep quality are still commonly found among vocational school students. This has a direct impact on their physical and mental health, as well as character building. An internal survey of 176 students at Telkom Banjarbaru Vocational School showed high rates of depression and  mood  disorders, indicating the  need  for  educational intervention to  raise  awareness of  the importance of a healthy lifestyle. This community service activity aims to improve students' knowledge and skills in understanding mental health, building sustainable discipline, and preparing balanced nutrition menus in accordance with the “My Plate” principle. The partner for this activity is Telkom Banjarbaru Vocational School  with  182  participants from  grade  X.  The  implementation methods included  lectures,  discussions,  practical  menu  planning  simulations,  and  pretest  and  posttest evaluations. The first day focused on education about mental health, character, and the relationshipbetween nutrition and psychological conditions, while the second day consisted of training in healthy menu planning and food  journaling. The results of  the  activity showed an increase in  students' knowledge of all the material, as demonstrated by a comparison of pretest and posttest scores. This activity also encouraged students to be more active in discussing and reflecting on their lifestyle habits. Overall, this education and training program can improve students' knowledge of healthy lifestyles and skills in preparing balanced nutrition as part of ongoing character building. Keywords: education; healthy living; mental health; nutrition; character education

Abstract

Background: Staphylococcus aureus is an opportunistic Gram-positive bacterium that can colonize the oral cavity and cause various infections such as oral abscesses, stomatitis, and post-dental procedure infections. The increasing problem of antibiotic resistance has encouraged the exploration of medicinal plants as alternative antibacterial agents. Sungkai (Peronema canescens) leaves are traditionally used by the Dayak Meratus community as herbal medicine and are known to contain bioactive compounds with potential antibacterial activity. Purpose: This study aimed to analyse the phytochemical content and antibacterial activity of sungkai leaf extract against Staphylococcus aureus. Methods: This research used a true experimental design with a post-test-only control group design. Methanol extract of sungkai leaves was prepared using the maceration method. Phytochemical analysis included determination of flavonoid, alkaloid, and steroid contents using spectrophotometric and gravimetric methods. Antibacterial activity was tested using the disc diffusion method on Mueller Hinton Agar against S. aureus at concentrations of 25%, 50%, 75%, and 100%. Clindamycin was used as a positive control and sterile distilled water as a negative control. Results: Phytochemical analysis showed that sungkai leaf extract contained flavonoids (85.47 mg/mL QE), steroids (26.797%), and alkaloids (18.436%). The antibacterial test showed inhibition zones that increased with extract concentration, namely 10.19 ± 0.23 mm (25%), 12.89 ± 0.43 mm (50%), 14.80 ± 0.41 mm (75%), and 17.72 ± 0.57 mm (100%). Conclusion Sungkai leaf extract contains several bioactive compounds and demonstrates antibacterial activity against Staphylococcus aureus, indicating its potential as a natural antibacterial agent.Keywords: Antibacterial Activity, Phytochemical Analysis, Staphylococcus aureus, Sungkai Leaf Extract.

Abstract

Natural products remain important sources of antioxidant compounds, particularly among underexplored tropical fruits. This study evaluated the antioxidant potential of Kweni (Mangifera odorata) fruit extract by integrating LC–MS profiling, in vitro assays, and molecular docking. Putative compounds were annotated by spectral-library matching. Hydroxyl radical (•OH) and hydrogen peroxide (H₂O₂) scavenging and metal-ion chelating activities were measured, and the corresponding half-maximal inhibitory concentrations (IC₅₀) were determined. Five flavonoid-related candidates (eriodictyol, astilbin, apigetrin, naringenin, and genistein) were selected for docking against Kelch-like ECH-associated protein 1 (KEAP1). The extract showed measurable activity in all three assays, with IC₅₀ values of 67.240 µg/mL for metal-ion chelation, 83.03 µg/mL for H₂O₂ scavenging, and 84.17 µg/mL for •OH scavenging. Among the selected candidates, astilbin and the tentatively annotated apigetrin produced the most favorable Vina scores (−10.2 kcal/mol) and predicted contacts within the modeled KEAP1 pocket. Because the compounds were putatively annotated and the assays used the whole extract, the observed activities cannot be assigned to individual constituents. The docking results indicate possible ligand–KEAP1 interactions but do not demonstrate KEAP1 inhibition, disruption of KEAP1–NRF2 binding, or NRF2 activation. Authentic standards, isolated compounds, biochemical binding assays, and cellular studies are required for confirmation.
